[Javascript] Trouble with id

[Troy III Ajnej]

Helo Del,
this code works as expected on both, IE and FX (strictmode): 
 
<a href="#" onMouseOver = toggle_visibility('hint4')><img src="../../image/icon_toggle.jpg" width="22" height="22" border="0"></a>
<span class = "hidden_hint" id=hint4> Add - <img src="../images/sq_root_7.gif" align="absmiddle"> to both sidesof the equation.</span>
 
function toggle_visibility(id) {  var e = document.getElementById(id);
  if(e.style.visibility != 'visible')   e.style.visibility = 'visible';  else   e.style.visibility = 'hidden'; } 
 
One thing I don't understand is what's the use of a toggle function if
there is no "onmouseout" event defined? Since you'll have to mouseover
twice to toggle it, consider defining the mouseout also:
<a href="#"onMouseOver = toggle_visibility('hint4') 
onMouseOut = toggle_visibility('hint4')>
...
Regards
